Onthe protrudingthreaded roo d `with which our end of the tube f is screwed `a hollow nipple t', carrying, to extend longitudinally through the tube f, an air-supply tube ft, terminating at its outer end coincident with the opening h in the nipple g in a needle-point 71,', adjacent to which small openings t2 are provided in the tube t'. A ne-bore tubec for conducting the liquid fuel xetends through the diaphragm c into the section A', preferably far into the latter, as shown, being supported in the diaphragm, and where it protrudesinto the mixing-chamber it is shown to be deflected to project its extremity forward in alinement with the minute nipple-opening h.

The mixing-chambersection A2 isprovided on the outer surface of its Wall with a hanger (shown as a suspension-hook Z) and in the head m, which closes its outer end, with a gas-outlet opening fn., surrounded b v a nipple o, into which is screwed a tubular gooseneck p.

The pyrographical tool B, in connection improved generator is shown in the drawings, may comprise any known or suitable construction, that illustrated invol ving,generally stated, a tube r,passing r through a handle portion r of material non-conductive of heat, such as cork or wood, the tube carrying at its outer end the hollow needle or point s to be rendered hot by the heat of the burning gaseous fuel within it for charring the Wood to be ornamented. In the point s, near its base, is shown an opening s for the escape of products of combustion, though a point adapted for merely scorching the surface of such wood has the extremity of its flattened end open for the emergence of the hot products of combustion, which are directed against the surface to be scorched by manipulating the tool B over it like a paintbrush, or by brushing, as this operation is termed. vThe tool is flexibly connected with the generator by rubber tubing t, coupled at one end to the rear extremity of the tube r and at its opposite end to the gooseneck p, the bent form of which prevents the rubber tubing from becoming kinked or flattened, as it might without such gooseneck attachment, with the effect of shutting off the gas-supply from the generator to the tool.

The air-pressure supply to the generator is provided through a suitable air-pumping medium, thatshown being the connected rubber bulbs C and C commonly provided for the purpose and flexibly connected with the generator A at the nipple t" by rubber tubing i.

To use the generator in the described connection, the operator hangs it at the hook Z, preferably over the edge of an upper pocket in his vest, (represented atDin Fig. 1,) thereby leaving one hand free to hold and Work the bulb C and his other hand to hold and guide the tool over the surface to be burned. By Working the bulb air is forced under pressure through the tube i and its apertures ft2 into the air-pressure holder f, whence it discharges into the mixing-chamber formed y with .the opening' h,

by the section A2 in quantity regulable by turning the nipple t" to vary according to desire the outlet at h by advancing toward or retracting from it the point 7L', Which thus, forms a Vneedle-valve. The bulb C need only be worked with sufficient frequency to maintain the bulb C more or less inflated. Vhile the air under pressure is discharging from the opening h, liquid fuel enters through the tube 7c from the reservoir Al into the chamber `A2 and therein mixes with the air and vaporizes, and vapor and gasification of the latter being enhanced in the progressof the mixture through the porous filling e, so that it forms a readily iniiammable and combustible gas Whenitleaves the mixing-chamber at the discharge-opening n to pass through the gooseneck p and tubing t into the tool B, where it is iginited through the opening in the point s.

As will be seen, the described construction of our improved generator greatly enhances the convenience'and facilitates vthe use of the tool with which it is employed and enables the supply by a slow, regular, and -easy airpumping operation of a sufficient quantity of compressed air to keep the supply-holderf therefor replenished and to provide a steady current of the air for gasifying the liquid` fuel, the compressed-air supply to the mixing-chamber being conveniently regulable by turning the nipple t" to open more or less the needle-valve device.

What we claim as new, and desire to secure by Letters Patent, is v l. In a gas-generator of the character described, the combination of a reservoir and a mixing-chamber connected therewith and provided with a gas-discharge opening, a compressed-air holder opening into said mixingchamber, an air-tube within and discharging into said holder and adapted to be connected with an air-compressor, and a supply-tube for liquid fuel leading from said reservoir into the mixing-chamber.

3. A gas generator of the character described, formed of tubular sections coupled endwise together, one section forming a reservoir for liquid fuel and being closed at its opposite ends, and the other section forming a mixing-chamber closed at its opposite ends, an air-pipe passing through said reservoir and opening into said mixing-chamber and adaptone end with an aired to be connected at ervoir for liquid fuel and being closed at its IIS opposite ends, andthe other section forming a mixing-chamber closed at its opposite ends and provided at its outer end With a gas-discharge opening having a gooseneck extension for a rubber-tube connection with a pyro` graphical or other tool, an air-pipe passing through said reservoir and opening into said mixing-chamber and adapted to be connected at one end with an `air-compressor, and a supply-tube for the liquid fuel leading from saidreservoir into said mixing-chamber and open therein to the compressed air discharged from said air-tube.
